Brocade switch Zoning and Fabric Operations

        When configuring zoning or other fabric-wide settings in a fabric that has products operating with different versions of FOS, it is recommended that the configuration be performed via an interface (such as WebTools) to a product with the most recent version of FOS. 

       Some older versions of FOS do not fully support newer hardware models, and problems may arise when configuring settings through these older products. 

       Zoning configuration in particular should never be performed through a switch operating with FOS v3.x in a fabric that also has products operating with newer releases of FOS firmware.
